- The Structural Study of Copper-binding Peptides: Implication in the Aggregation of Amyloid-β Peptides

Two pathways are proposed to explain the fibril growth from soluble Aβ peptide. Two Aβ peptides chelate with copper ion in either parallel or anti-parallel orientation, and then the aggregate grows to form fibril by the incoming metallated Aβ peptides.

The photoreaction of three cobaloxime complex crystals with chiral 1-tert-(butoxy- carbonyl)ethyl group showed the inversion of the chiral group with retention of the single crystal form. The reaction cavity well explains the reaction mechanism.
- Selective Hydrogenation of Acetylene over SBA-15 Supported Au—Cu Bimetallic Catalysts

SBA-15 supported Cu-Au bimetallic nanoparticles are studied under different Cu/Au ratios and temperature. The addition of gold promotes the catalytic performance, reducing the amount of oligomers formed on the catalyst's surface. A synergistic effect between copper and gold is also displayed. The bimetallic catalyst with Cu/Au ratio at 1/3 has both better conversion and selectivity between 160-200 °C, providing the opportunities to lower the operating temperature (>200 °C) of copper.
- A Large Manganese-doped Polyoxotitanate Nanocluster: Ti14MnO14(OH)2(OEt)28

A large manganese-doped polyoxotitanate nanocluster, Ti14MnO14(OH)2(OEt)28, has been synthesized and analyzed by crystallographic, spectroscopic and theoretical methods. The Mn doping of the polyoxotitanate significantly reduces the band gap, confirming the significance of transition metal doping in photocatalysis applications.
- Salt-Dependence of Homology Searching Step by RecA Nucleoprotein Filaments
Song-Mao Liao, Hung-Yi Wu and Hung-Wen Li

We applied lateral magnetic tweezers to stretch duplex DNA molecules (Lambda DNA, 48,502 bp) in order to monitor the homology searching step by RecA nucleoprotein filaments at the single-molecule level. From individual searching events, the diffusion coefficient of the RecA nucleoprotein filament is determined to be ∼ 0.5-1 μm2/s. The nearly salt-independence of the diffusion coefficients of RecA nucleoprotein filaments implies that our observed RecA searching events were mainly carried out by the one-dimensional sliding mode.
